摘　　要：依据影响滑坡稳定的定性信息和定量数据,采用模糊信息优化理论的方法,对干海子滑坡样本指标量化数据进行优化处理,建立了影响滑坡稳定的9个因素指标之间的模糊关系模型。针对干海子滑坡地质环境特点,建立了干海子滑坡和3个样本间的9个因素对照表,采用类比和线性方法求出了干海子9个因素的指标值,利用模糊关系模型及二级模糊近似推论方法分析了各因素的影响,并对该滑坡的稳定性进行了评价。According to the qualitative information and quantitative data affecting the stability of a landslide, a fuzzy relational model is established for the 9 factors indexes which affect stability of the Ganhaizi landslide by using the sample quantified indexes optimized by the fuzzy information optimization theory. A 9 - factor comparison table for Ganhaizi landslide and 3 specimens is also established in view of its geo - environmental characteristics. The values of 9 - factor indexes are calculated by analogy and linear methods. The influences of each factor are also analyzed by the fuzzy relationship model and two - stage approximate reasoning method, and the stability of landslide is evaluated.
